VNC> helpdesk situation

[jesskung@brel.com]

Hi all

We are trying to use VNC for a helpdesk situation and would appreciate some 
help. Here goes...

1. End user runs VNC server. 
2. VNC server prompt for password. 
3. Login password is verified against NT domain login password or 
   MS network login password
4. After server is ran, helpdesk personnel runs viewer to connect to 
   end user server via IP address of server.
5. Connection is allowed by passing checking of password.

How can this be done?

Many thanks in advanced for any help.......   :)

Regards,
Jessica
